Raises a question worth testing. It does not answer one.
This narrative review proposes that high-fat diets contribute to neurological disease through mechanistic pathways including neuroinflammation, oxidative stress, mitochondrial dysfunction, and gut-brain axis disruption, with downstream effects on amyloid-β deposition, tau phosphorylation, dopaminergic neuron loss, and serotonin homeostasis. The text synthesises existing literature but reports no new empirical evidence, primary endpoints, or quantified associations to substantiate causal claims.
Journal article. Conceptual; no specific human or animal population studied.
HFDs lead to metabolic imbalances including insulin resistance, dyslipidemia, and systemic inflammation Pathophysiological mechanisms include neuroinflammation, oxidative stress, mitochondrial dysfunction, and gut-brain axis dysfunction In Alzheimer disease, HFD-induced changes enhance amyloid-β deposition and tau hyperphosphorylation leading to synaptic dysfunction and cognitive impairment

This review does not provide sufficient evidence to guide clinical practice or recommend dietary interventions. Clinicians should consider it an overview of proposed mechanisms rather than a basis for patient counselling or treatment decisions.
This is a narrative review synthesizing mechanistic hypotheses about high-fat diet and neurological disease without reporting new empirical data, primary outcomes, or comparative evidence.

What is missing. This record has no reported figures. That is a gap in the analysis, not a judgement about the study.
The brain and the spinal cord make up the central nervous system (CNS), which regulates important sensory, motor, cognitive, and autonomic functions. Evidence is accruing to the fact that high-fat diets (HFDs) play a significant role in the development and progression of neurological diseases. HFDs are unhealthy since the chronic use leads to metabolic imbalances that result in insulin resistance, dyslipidemia, and systemic inflammation with adverse effects on the well-being of the brain. Some of the most severe pathophysiological events caused by such metabolic changes include neuroinflammation, oxidative stress(OS), mitochondrial dysfunction, and gut-brain axis dysfunction. These mechanisms enhance the deposition of amyloid-b and hyperphosphorylations of tau in the case of Alzheimer disease(AD) which results in dysfunction of the synapses and impairment of cognition. HFD causes oxidative lesions and inflammation which increase the death of dopaminergic neurons in the substantia nigra when it occurs in the case of Parkinson disease. In addition to this, HFD may modify the homeostasis of the neurotransmitters particularly those of serotonin and hence one becomes more susceptible to depression. The review provides a detailed explanation of the molecular mechanisms of the relationship between the application of high-fat diets and the development of neurological problems and identifies the potential treatment strategies that can be used as prevention and treatment options.
